I know that latter teenagers are "maturer" than before, so I think the sex education is extremely important. There are some pieces of news about abortion, teenagers who cause an abortion lack for knowledge. An abortion is not only illegal but not good for girls. And I think the sex education should be applied to earlier teenagers.

　　In my opinion, the older people have a bad memory for everything and they get dementia easily. Not only dementia but other pathologies they can get easily, like high blood pressure, high cholesterol, and so on. These diseases may increase the risk of stroke, we should take care of them. Just like my grandfather, he seems to have a bad memory for everything. I try my best to let him recall everything. If I don't do this, I'm scared that he would get stroke easily.

High-fat, high-carb meals more harmful to obese

In previous research they found that obese individuals have higher levels of oxidative stress and inflammation than normal-weight individuals. They also demonstrated that eating a high-fat, high-carb meal increased oxidative stress and inflammation in normal-weight people.(→The third paragraph) In another study, Dandona and his colleagues demonstrated that a high-fruit, high-fiber meal with the same calorie content as the fast food meal tested in the current study produced no increase in oxidative or inflammatory stress.(→The sixth paragraph)→"the news"http://news.yahoo.com/s/nm/20071228/hl_nm/meals_obese_dc;_ylt=AuT80wOQk4RRPJ9SK0wz7Y2ISbYF

A new study shows that the obese people eat more high-fat and high-crab can be easier to have higher levels of oxidative stress and inflammation than normal-weight people. People who have oxidative stress and inflammation easily got atherosclerosis, heart attack and stroke. People should eat more high-fruit and high-fiber meal so that people can make their bodies stay healthy.

I believe that some people try to be on a diet because they want to stay healthy not for good looking. The obese people are indeed easier to get diseases than normal weight people, like heart attack, high blood pressure, and so on. People really should eat much fruit and vegetables and avoid high-fat and high-crab meal, it's really terrible. For your own good, try to eat much healthy food.
